Dialogue: CAUSE AND EFFECT

Dialog : Cause And Effect About Chemical Reaction
We can divide the most common linking words and expressions of cause and effect into four group :
1. Coordinating Conjunctions: for (cause), so (effect)
2. Subordinating Conjunctions: because, since, if, whenever, so that, as (cause)
3. Conjunctive Adverbs: therefore, for this reason, as a result, thus, that is why, consequently (effect)
4. Preposition: because of, reasons for, consequences of, due to (cause)
Jelpa: hi Aulia!
Aulia: hello Jelpa!
Jelpa: Aulia, I have a magic attraction.
Aulia: Really? Show me!
Jelpa: I cannot do it here. So instead you guess what would happen if I dipped the paper money into a glass of alcohol and water, and then I burned it. What is the effect?
Aulia: I know the answer. As a result is that the paper money are not burned.
Jelpa: wow. That’s true. Where do you know?
Aulia: I have seen the videos on the internet.
 Jelpa: Thus why do you think the paper money does not burn?
Aulia:  alcohol can form a thin liquid on a sheet of money. Because alcohol is flammable and its density is less than water, the alcohol remains in the top layer. The money sheet will not burn because alcohol cannot seeps into the tightly woven money webbing.
 Jelpa: Then if I use plain paper, what is the effect? Whether the paper will not burn?
Aulia: plain paper cannot be used for this experiment, because alcohol is absorbed much more quickly on woven loose paper fibers. So the effect is the paper will come burning.
Jelpa: Well like that. I wanted to try to do it right away.
Aulia: Be careful in doing so. Keep your face away from the solution. Alcohol is very dangerous because it is volatile.
Jelpa: Yes just be calm down. I will be very careful. After doing so I will be a great magician. Ha ha.
Aulia: LOL. That is not a magic attraction. It's just one of those amazing chemical reactions. 
Jelpa: okay Aulia. It’s time to go back to class.  See you later.

Aulia: bye Jelpa. See you!

    Except paper money, what we can use to try this experiment?

      We can also use filter paper. Filter paper has a thick enough fiber so that alcohol is not absorbed by filter paper because it is blocked by a layer of water

    Why alcohol is flammable?

      The nature of alcohol when interacting with the air (put in the open) then the alcohol more easily bound to the gas so that alcohol more quickly evaporated, because the faster evaporation that causes alcohol more flammable

    What will happen if the paper money we dipped into a water without alcohol?

      Water is extinguishing fire. If we do the experiment without alcohol, then the paper money will not burn.

      Chemically the word "burn" or "burning" means more or less "reacting a compound or element with oxygen"
      The water of the compound is H2O, two carbon atoms with one oxygen atom. Meaning more or less, water is the result of "combustion" of hydrogen. Burning results can not be burned anymore.
      While alcohol, for example ethanol compounds C2H5OH, although it contains one oxygen atom, but still has two carbon atoms and four burning hydrogen atoms.

USING ENGLISH TO PREDICT RENDEMENT OF A REACTION (resume 7)

RENDEMENT OF A REACTION The chemical rendement, the rendement of the reaction, or rendement refers to the amount of reaction product produced in the chemical reaction. Absolute rendement can be written as weight in grams or in moles (molar yield). The relative yield used as a calculation of the effectiveness of the procedure is calculated by dividing the amount of product obtained in moles by the theoretical yield in moles:   Fractional yield = actual rendement divided by theoretical rendement   To obtain a percentage yield, multiply the fractional yield by 100%. One or more reactants in chemical reactions are often used redundantly. The theoretical rendement is calculated based on the number of moles of the limiting reagent. For this calculation, it is usually assumed there is only one reaction involved. The ideal chemical yield value (theoretical rendement) is 100%, a value highly unlikely to be achieved in its practice. Calculate the percent of rendemen that is ...

VIDEO (Alkane derived compounds)

Let's check this video https://youtu.be/UDIupJRhosI ALCOHOL All alcohols contain the -OH group, for example ethanol. Alcohol has similar chemical properties. All ethers contain an -O- group, for example dimethylters. Ether has similar chemical properties. Groups such as -OH and -O- are replaced in hydrocarbon chains called functional groups. They dominate chemical molecules and provide characteristic properties. The hydrocarbon chain is the symbol of R. The naming of organic compounds is divided into two, named naming according to IUPAC (systematic name) and trivial naming (common name). Naming according to IUPAC is established by IUPAC (International Union and Pure Applied Chemistry), whereas trivial naming is a naming system that has been known before the establishment of the naming system according to the IUPAC. The trivial name is more popular in industry and commerce because of its easy mention. Nomenclature of Alcohol (alkanol) IUPAC: Alcohol is a derived compound ...

VOCABULARY OF CHEMISTRY

Acid - Acids are compounds with a pH less than 7 that form hydrogen ions when dissolved in water. Acids react when in contact with bases and some metals to form salts. Alkali metal - Alkali metal is an element in the first column of the periodic table with the exception of hydrogen. Alkaline earth metal - Alkaline earth metal is an element in the second column of the periodic table. Allotropes - Allotropes are different shapes in which the same element can exist. For example, carbon elements can be either allotropes of graphite or allotropes of diamonds. Atoms - the atom is the fundamental unit of matter and the smallest unit of an element. It consists of a core surrounded by a cloud of electrons. Bases - are substances with a pH higher than seven. A base is defined as a contributor to a pair of valence electrons. Biochemistry - The study of chemical processes related to living organisms. Loads - The attraction between the atoms that make up the chemicals. B...
